Roof-top tent aerodynamic shell and hinge mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roof-top tents for vehicles are inconvenient to move and assemble, obstruct drivers' vision with fluttering waterproof covers, and create resistance during driving, while also having a bulky and complex structure.
Innovation Solution
A roof-top tent design featuring a first and second cover portion with a hinge connection, a waterproof portion, and a tent portion, where the cover portions are fixedly installed on the vehicle's roof, allowing for a folding mode to minimize space and an unfolding mode for easy setup, with a waterproof system that detaches to prevent wind interference and maintain driver visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional waterproof cover made of tarpaulin is used to cover the roof-top tent during driving, then the tent is protected from rain, but the wind infiltrates into the cover causing it to flutter and interfere with the driver's vision, and the cover creates resistance during driving
Solution Approach 1:
The patent replaces the conventional tarpaulin cover with a streamlined cover having a smooth, aerodynamic shell shape. This flexible shell design maintains waterproof protection while eliminating wind infiltration and fluttering, thus resolving the contradiction between waterproof reliability and wind interference.
Solution Approach 2:
The cover is designed to be detachable and convertible between different states (attached for protection, detached or streamlined for driving). This dynamic capability allows the system to adapt to different operational requirements, reducing wind resistance during driving while maintaining waterproof protection when needed.
2Reliability
If a conventional tarpaulin waterproof cover is used on the roof-top tent, then waterproof protection is provided, but the cover has poor appearance and creates resistance during driving
Solution Approach 1:
The streamlined cover with its smooth, aerodynamic shell shape replaces the conventional tarpaulin design. This shell structure provides both excellent waterproof protection and superior aerodynamic profile, eliminating the appearance and resistance problems while maintaining reliability.
3Ease of operation
If the tent is designed with a folding mode for compact storage, then ease of transport is improved, but the structure becomes more complex requiring precise assembly
Solution Approach 1:
The tent is divided into modular segments (first and second cover portions, tent portion) that can be independently assembled and folded. This segmentation enables compact folding for transport while simplifying the overall assembly process, as each module can be independently handled and connected through simple coupling mechanisms.
Solution Approach 2:
The folding mechanism allows the tent portion to be nested within the cover portions when folded, creating a compact storage configuration. This nesting approach reduces transport volume while avoiding complex folding mechanisms, as the tent simply nests within the protective cover structure.

AI summary
A roof-top tent for a vehicle. The roof-top tent includes a first and second cover portion including a first and a second plate member provided in a plate shape; a hinge connection portion rotatably connecting the first and the second cover portion and the second cover portion; a waterproof portion having both ends fastened to the first and the second cover portion; and a tent portion coupled to the first and the second cover portion, where one of the first and the second cover portion is provided so as to be fixedly installed on a roof of a vehicle, where the roof-top tent has a folding mode and an unfolding, and where the waterproof portion is detachably fastened to a rim of the first cover portion and the second cover portion in the folding mode to close the space between the first cover portion and the second cover portion.
